Description

joint fixing structure

technical field

The invention relates to a joint fixing structure, in particular to a joint inserted in a product with a high communication vibration environment (such as mobile phones, communication equipment on airplanes or automobiles...), which can improve the external force of the environment during use, It also has a moisture-proof setting and can obtain better transmission power. the

Background technique

At present, there are quite a lot of joint forms developed and applied in various communication products in the industry. In order to make the two joint components (as shown in Figure 1) elastically clamped when they are assembled, the industry will use the needle 20 which has a guiding function. The outer peripheral edge of the receiving terminal 10 is provided with a split groove 101 to be inserted between the holes 301 of the other end connector 30, so that the peripheral edge 102 of the receiving terminal 10 with the split groove 101 can be elastic and urgently resist the ring inside the hole 301 of the connector 30. In the groove 302, at the same time, the needle 20 in the receiving terminal 10 is buckled into the inside of the needle 40 at the corresponding end of the joint 30, so as to achieve the required communication connection between the two joint components. the

However, in this type of joint, when the receiving terminal 10 is fully assembled into the joint 30, there is a gap between the split groove 101 formed on the peripheral edge 102 of the active end and the hole 301 of the joint 30, causing the outside air to enter along the gap. In the joint assembly, after a period of time, the internal components begin to oxidize and rust, causing problems in the transmission efficiency of the joint assembly. At the same time, the discontinuous section formed by the sectional groove 101 of the receiving terminal 10 is located at the contact position of the pins 20 and 40 of the two joint members, resulting in a large loss of high-frequency output efficiency, plus the elasticity generated by the sectional groove of the receiving terminal. There is only one part of the acting force, and the buffering and shock absorbing effect provided during external vibrations is also limited. the

Therefore, in order to solve this problem and improve the transmission power of the joint assembly, the relevant industry chooses to use beryllium copper to make it, but beryllium copper is a high-cost material and is a high pollutant that will damage the environment, and its anti-vibration function is not high. . the

Contents of the invention

In view of the above problems, the main purpose of the present invention is to provide a joint fixing structure, so that even if beryllium copper is not used to manufacture the joint member, it can achieve high transmission efficiency and the effects of vibration and moisture resistance. the

In order to achieve the above object, the present invention provides a joint fixing structure, which includes a high-frequency joint composed of a first joint and a second joint; There is more than one sectional groove on the receiving periphery of the second joint, and more than one groove is provided on a section of the outer periphery of the second joint to embed a corresponding number of flexible O-rings so that the receiving pipe section fits therein; in the first joint The end is provided with more than one section of inclining ring edge with a slope, which is firmly against the ring groove with more than two sections of slope provided in the corresponding paragraph of the second joint; the needle of the second joint cuts into the One end of the corresponding needle of the first connector is kept in close abutment. the

In the above-mentioned technical solution of the present invention, a nut is sleeved on the outside of the high-frequency joint composed of the first and second joints. the

In the above-mentioned technical solution of the present invention, one end of the first and second joint components is respectively combined with an adapter as a receiving part for connecting the required assembly components. the

In the above-mentioned technical solution of the present invention, a cut-off slip ring surface is provided at the inner side of the first and second joints adjacent to the insulator to prevent the insulator from moving. the

In the above-mentioned technical solution of the present invention, the end of the receiving peripheral edge of the first joint forms a section of convex ring edge that is constantly elastically retracted, and the two sections of the section that are recessed on the side of the second joint's rear receiving section have a slope The ring groove of the ring groove is urgently restricted, and the internal thread section of a nut is screwed into the direction of the second joint along the thread section of the first joint, and the opening at the other end of the nut forms a section of inclination The section is tight against the convex ring edge of the first joint, and the two slopes of the ring groove at the corresponding position of the convex ring edge and the second joint are in a preferably tight azimuth restriction. the

By adopting the above-mentioned technical solution, since the sectional groove of the first joint presents a discontinuous section after assembly, the communication quality can be ensured not only by the needles in the two joints, so that the present invention is applied to products with high communication vibration frequency , The inserted joint can also obtain better transmission power. Secondly, by adding a nut on the outside of the joint composed of the first and second joints, the present invention can maintain a better assembly positioning when joining large-scale cables and antennas with external force. Furthermore, in the present invention, adapters can also be combined at one end of the first and second joints constituting the joints, which can be used as receiving parts for connecting required assembly components. Moreover, in the present invention, a section of convex ring with constant elasticity and retraction is provided at the end of the receiving peripheral edge of the first joint, so that the two sections of sloped ring grooves recessed on the side of the second joint's rear receiving section can be used as an emergency. The azimuth of the nut is limited, and the internal thread section of a nut is screwed in along the thread section of the first joint towards the direction of the second joint, so that an inwardly inclined section formed at the opening of the other end of the nut can be urgently against the first joint. The protruding ring of the first joint, the protruding ring and the ring grooves with two slopes at the corresponding parts of the second joint are in a better tight azimuth restriction. the
